I communicated w/ him; He did contract a Giardia infection on the long hike prior to the onset of the symptoms; also, the ATSDR Profile on ClO2 reports no long term human illnesses reported and a 2 year animal study had a NOAEL well above the concentration used by the disinfectant

Thanks - to everyone - it was educational for me. I pointed him to the resources mentioned - still suggested he contact a toxicologist. And told him the comparisons - municipal drinking waters and soft drinks.

I am inclined to agree - any chronic problems are other sources - such as the bugs the stuff doesn't get - by the company's own admission or other exposures along the way.

When my dad worked for a beverage company, he hauled tank cars of fruit juice concentrate and soft drink syrups for a beverage manufacturing company in Washington. He had to have a haz mat endorsement on his commercial driver license because the commodities hauled were considered a corrosive hazard (pH < 2). The truck didn't have to be placarded because the materials were for human consumption (guess who came to that regulation writing party?) but he did have to have all of the other haz mat requirements in place. I don't drink fruit juice from concentrate and I rarely drink soda, preferring iced tea and sparkling water. Or a nice lager on a hot day. J

According to Snopes http://www.snopes.com/cokelore/acid.asp, Coca Cola contains 11 to 13 g phosphoric acid per gallon of syrup. This works out to be 0.20 to 0.30% of the total formula. The syrup is diluted with carbonated water for serving so that should reduce the phosphoric acid to 0.02 to 0.03% or less.

This is a reporter that is looking for some help on a story - anyone what to contact him? There is a part A and a part B - the part B has phosphoric acid - both MSDSs (SDSs) put out by the company indicate irritation if ingested at large dosages.

I would gladly take you up on your offer to be put in touch with any colleagues you think might be able to help.

One of the most popular water treatment options amongst Appalachian Trail thru-hikers is Aquamira, a chlorine dioxide chemical solution. As you point out, the dose makes the poison- however due to the extreme demands of long-distance backpacking, it's common to ingest between 5-8 liters of water per day. Multiply this times 4-6 months (how long it takes to cover the full distance of the trail). Since my thru-hike in 2011, I have battled severe digestive issues, and I have talked with others (who've used Aquamira) who say the same. If there is any truth to this being unsafe in high volumes, I'd like to help spread the word and prevent future hikers from suffering.

Hello Zach,

Here's another pitch from a HARO source! Hope you find the perfect match for your story.

Best,

Pitch Title: Your request on chlorine dioxide

Pitch Contents:

You really need to contact the American Chemical Society - they can putyou in touch with the correct person. My recommendation is that you needto talk with an industrial hygienist as they are more trained in howchemicals are used/misused and toxicity levels. A chemical toxicologistis someone else you might talk with. I can put you in touch with acouple of colleagues of mine that may be able to help. As with mostthings it is a matter of dose. -- <pre>Frankie Wood-Black, Ph.D., REM, MBAPrincipal - Sophic Pursuitswww.sophicpursuits.com6855 Lake RoadPonca City, OK 74604fwblack**At_Symbol_Here**sophicpursuits.com580-761-3703</pre>
